Gmail

Google email service for sending, receiving, searching, and organizing messages.

Fits inbox workflows that draft messages, sort mail with labels, archive completed threads, and react when matching messages or attachments arrive.

Example Use Cases

These are the Gmail actions Snow can use when building apps with you. Connecting an account does not make Snow run these on its own.

Batch modify Gmail messages

Modify labels on multiple Gmail messages in one efficient API call. Supports up to 1,000 messages per request for bulk operations like archiving, marking as read/unread, or applying custom labels. High-volume calls may return 429 rateLimitExceeded or 403 userRateLimitExceeded; apply exponential backoff.

Create email draft

Creates a Gmail email draft. While all fields are optional per the Gmail API, practical validation requires at least one of recipient_email, cc, or bcc and at least one of subject or body. Supports To/Cc/Bcc recipients, subject, plain/HTML body (ensure `is_html=True` for HTML), attachments, and threading. Returns a draft_id that must be used as-is with GMAIL_SEND_DRAFT — synthetic or stale IDs will fail. When creating a draft reply to an existing thread (thread_id provided), leave subject empty to stay in the same thread; setting a subject will create a NEW thread instead. HTTP 429 may occur on rapid creation/send sequences; apply exponential backoff.

Delete Draft

Permanently deletes a specific Gmail draft using its ID with no recovery possible; verify the correct `draft_id` and obtain explicit user confirmation before calling. Ensure the draft exists and the user has necessary permissions for the given `user_id`.

Delete thread

Tool to immediately and permanently delete a specified thread and all its messages. This operation cannot be undone. Use threads.trash instead for reversible deletion.

Fetch emails

Fetches a list of email messages from a Gmail account, supporting filtering, pagination, and optional full content retrieval. Results are NOT sorted by recency; sort by internalDate client-side. The messages field may be absent or empty (valid no-results state); always null-check before accessing messageId or threadId. Null-check subject and header fields before string operations. For large result sets, prefer ids_only=true or metadata-only listing, then hydrate via GMAIL_FETCH_MESSAGE_BY_MESSAGE_ID.

Fetch message by message ID

Fetches a specific email message by its ID, provided the `message_id` exists and is accessible to the authenticated `user_id`. Spam/trash messages are excluded unless upstream list/search calls used `include_spam_trash=true`. Use `internalDate` (milliseconds since epoch) rather than header `Date` for recency checks.

Get Draft

Retrieves a single Gmail draft by its ID. Use this to fetch and inspect draft content before sending via GMAIL_SEND_DRAFT. The format parameter controls the level of detail returned.

Get Gmail attachment

Retrieves a specific attachment by ID from a message in a user's Gmail mailbox, requiring valid message and attachment IDs. Returns base64url-encoded binary data (up to ~25 MB); the downloaded file location is at data.file.s3url (also exposes mimetype and name; no s3key). Attachments exceeding ~25 MB may be exposed as Google Drive links — use GOOGLEDRIVE_DOWNLOAD_FILE when a Drive file_id is present instead.

List Drafts

Retrieves a paginated list of email drafts from a user's Gmail account. Use verbose=true to get full draft details including subject, body, sender, and timestamp. Draft ordering is non-guaranteed; iterate using page_token until it is absent to retrieve all drafts. Newly created drafts may not appear immediately. Rapid calls may trigger 403 userRateLimitExceeded or 429 errors; apply exponential backoff (1s, 2s, 4s) before retrying.

Move to Trash

Moves an existing, non-deleted email message to the trash for the specified user. Trashed messages are recoverable and still count toward storage quota until purged. Prefer this over GMAIL_BATCH_DELETE_MESSAGES when recovery may be needed. For bulk operations, use GMAIL_BATCH_MODIFY_MESSAGES or GMAIL_BATCH_DELETE_MESSAGES instead of repeated calls to this tool.

Triggers

These are the trigger events currently available for Gmail.

Email Sent

Triggers when a Gmail message is sent by the authenticated user. It polls the 'SENT' label and emits metadata including sender, recipients, subject, timestamp, and thread ID.

New Gmail Message Received Trigger

Triggers when a new message is received in Gmail.
